Taiwan Semiconductor Corporation HER1602GH

Overview

HER1602GH from Taiwan Semiconductor is an AEC-Q101-qualified high-efficiency ultrafast rectifier in TO-220AB package, rated for 100 V repetitive peak reverse voltage (V_RRM), 16 A average forward current (I_F), and 125 A non-repetitive surge current (I_FSM). It delivers low 1.0 V forward voltage at 8 A and 25°C, enabling high-efficiency operation in automotive DC/DC converters and switching inverters.

For engineers reviewing the HER1602GH datasheet, HER1602GH pinout, HER1602GH application, or HER1602GH equivalent, key selection criteria include its AEC-Q101 qualification, 100 V V_RRM, 1.0 V V_F @ 8 A, 50 ns reverse recovery time (t_rr), and TO-220AB thermal performance with R_θJC = 1.5 °C/W.

Technical Context

This device is a dual-die, single-phase ultrafast recovery rectifier optimized for high-frequency switching topologies. Its 50 ns t_rr and low junction capacitance (80 pF @ 4 V) minimize switching losses and EMI generation in SMPS operating above 50 kHz.

The TO-220AB package provides robust thermal conduction to heatsinks via the metal tab (anode-connected), supporting continuous 16 A operation at T_J ≤ 150°C when mounted with ≤0.56 N·m torque and proper thermal interface material.

FAQ

What is the maximum junction temperature rating for HER1602GH?

The HER1602GH has a maximum junction temperature (T_J) of +150°C, validated across its full operating range from –55°C to +150°C per AEC-Q101 requirements. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial enclosures when mounted with appropriate heatsinking and thermal interface material. The HER1602GH maintains specified electrical parameters within this range.

Is HER1602GH pin-compatible with standard TO-220AB rectifiers?

Yes, HER1602GH uses the industry-standard TO-220AB outline with identical mechanical dimensions, lead spacing, and mounting hole location. Its pinout-tab = anode, left lead = cathode, right lead = NC-is consistent with single-diode TO-220AB rectifiers. No PCB layout changes are required when replacing legacy 100 V rectifiers in the same package, provided thermal and electrical margins are verified.

Does HER1602GH support freewheeling applications in inductive switching circuits?

Yes, HER1602GH is specifically designed for freewheeling applications, as confirmed by Taiwan Semiconductor's official documentation. Its 50 ns reverse recovery time and 125 A surge rating allow it to safely clamp inductive kickback in motor drivers, solenoid controllers, and relay interfaces without voltage overshoot exceeding its 100 V V_RRM rating. The HER1602GH's low V_F also minimizes power loss during freewheeling conduction.

What does the "H" suffix in HER1602GH signify?

Per Taiwan Semiconductor's ordering information, the "H" suffix in HER1602GH explicitly denotes AEC-Q101 qualification. This means the HER1602GH has undergone and passed the full suite of stress tests defined in the AEC-Q101 standard-including HTGB, HTRB, AC/DC life test, and temperature cycling-ensuring reliability for automotive electronic components. Non-H variants (e.g., HER1602G) lack this qualification.

How does HER1602GH's thermal resistance compare to similar rectifiers?

HER1602GH specifies a junction-to-case thermal resistance (R_θJC) of 1.5 °C/W, measured per JEDEC standards. This value is among the lowest for TO-220AB ultrafast rectifiers rated at 16 A, reflecting optimized die attach and internal thermal path design. When paired with a properly mounted heatsink, this enables sustained 16 A operation at case temperatures up to 100°C-critical for compact, high-power-density automotive and industrial power supplies using the HER1602GH.
